Body Needs Good Bacteria
We try to avoid germs to stay healthy but there is actually some "good bacteria" that our body needs they're called "probiotics". People with some infections and intestinal problems use probiotics and they're being studied for benefits in colon cancer, skin infections and irritable bowel syndrome.
Most are in pill form, but yogurt is another way to get good bacteria regularly as long as it says "active cultures" on the label. Experts say there are no side effects from taking probiotics.
